Method and system for adapting use of a radio link between a remotely controlled device and an operator control unit

1. A method for adapting use of a wireless link by a remotely controlled device communicating a video stream to an operator control unit used to control the remotely controlled device, the method comprising the steps of:

obtaining at the remotely controlled device a value for quality of the wireless link from measurements performed by the remotely controlled device;

determining, at least in part, directly from the value of the quality of the wireless link, at least one of a value of frames per unit time, a value of frame resolution, and a level of compression; and

providing the compressed video stream for transmission from the remotely controlled device to the operator control unit using at least one of the value of frames per unit time, the value of frame resolution, and the level of compression of each frame;

wherein the remotely controlled device performs each step continuously and in real time;

wherein the remotely controlled device self-determines how to perform each step independently without preset per device static parameters directing how the steps are performed;

wherein the remotely controlled device performs each step without relying on feedback information from a network layer of a communication protocol; and

wherein the operator control unit used to control the remotely controlled device via the wireless link controls at least one of the remotely controlled device's motion, physical location relative to the operator control unit, and functions separate and distinct from the steps performed by the remotely controlled device as it dynamically adapts the wireless link.

2. A method as in claim 1 , wherein in determining the value of frames per unit time or the value of frame resolution, the remotely controlled device performs the steps of:

obtaining a value for rate of motion of the remotely controlled device;

determining the value of frames per unit time based on the value for rate of motion; and

determining the value for frame resolution based on the value of frames per unit time and based on the quality of the wireless link.

3. A method as in claim 1 , wherein the wireless link is a radio link.

4. A method as in claim 1 , wherein the wireless link is an optical link.

5. A method as in claim 1 , wherein the wireless link is a sound wave link.

6. A remotely controlled device, configured for adapting use of a wireless link by the remotely controlled device in communicating a video stream to an operator control unit used to control the remotely controlled device, comprising:

video throttling means, for obtaining a value for quality of the wireless link from measurements performed by the remotely controlled device, and based at least in part, directly or indirectly on at least one of the value for quality of the wireless link, a value of frames per unit time, and a value of frame resolution; and

video controller/encoder means, for using at least one of the value of frames per unit time, the value of frame resolution, and at least a level of compression of each frame in providing the compressed video stream for transmission from the remotely controlled device to the operator control unit;

wherein the video throttling means is configured to: obtain a value for rate of motion of the remotely controlled device;

determine the value of frames per unit time based on the value for rate of motion; and

determine the value for frame resolution based on the value of frames per unit time and based on the quality of the wireless link.

7. A remotely controlled device as in claim 6 , wherein the wireless link is a radio link.

8. A remotely controlled device as in claim 6 , wherein the wireless link is an optical link.

9. A remotely controlled device as in claim 6 , wherein the wireless link is a sound wave link.
